Method Overloading-2

Example6:-

class Student
{
void disp(int a,long b)
{
System.out.println("This is Two[int,long] argument disp");
}
void disp(long a,int b)
{
System.out.println("This is Two[long,int] argument disp");
}
}
class Test
{
public static void main(String[]args)
{
Student s=new Student();
s.disp(100l,200);
s.disp(100,200L);
}
}

Output:-

C:\JAVATECH>javac Test.java
C:\JAVATECH>java Test
This is Two[long,int] argument disp
This is Two[int,long] argument disp
Method overloading in inheritance


Example7:-


class Teacher
{
void disp(double d)
{
System.out.println("double argument Teacher class method");
}
}
class Student extends Teacher
{
void disp(float f)
{
System.out.println("float argument Student class method");
}
}
class Test
{
public static void main(String[]args)
{
Student s=new Student();
s.disp(100);
s.disp(200);
}
}


Output:-

C:\JAVATECH>javac Test.java
C:\JAVATECH>java Test
float argument Student class method
float argument Student class method


Example8:-


class Teacher
{
protected void disp(double d)
{
System.out.println("double argument Teacher class method");
}
}
class Student extends Teacher
{
void disp(float f)
{
System.out.println("float argument Student class method");
}
}
class Test
{
public static void main(String[]args)
{
Student s=new Student();
s.disp(100);
s.disp(200.50);
}
}


Output:-

C:\JAVATECH>javac Test.java
C:\JAVATECH>java Test
float argument Student class method
double argument Teacher class method

Example9:-


class Teacher
{
void disp(double d)
{
System.out.println("double argument Teacher class method");
}
}
class Student extends Teacher
{
void disp(float f)
{
System.out.println("float argument Student class method");
}
}
class Test
{
public static void main(String[]args)
{
Student s=new Student();
s.disp(100.50);
s.disp(200.50);
}
}


Output:-
C:\JAVATECH>javac Test.java
C:\JAVATECH>java Test
double argument Teacher class method
double argument Teacher class method

Example10:-


class Teacher
{
void disp(double d)
{
System.out.println("double argument Teacher class method");
}
}
class Student extends Teacher
{
void disp(float f)
{
System.out.println("float argument Student class method");
}
}
class Test
{
public static void main(String[]args)
{
Student s=new Student();
s.disp(100.50f);
s.disp(200.50f);
}
}

Output:-

C:\JAVATECH>javac Test.java
C:\JAVATECH>java Test
float argument Student class method

float argument Student class method

Inner classes

Inner Classes:- class inside class or interface called inner class or nested class. Advantage of inner classes is grouping multiple classes and interfaces into a single class. Another big advantage of inner class is that inner class can happily access all the data or variables of outer class directly. Types of Nested classes:- There are two types of nested classes static and non-static nested classes. (A)Non –static inner classes:- 1)     Member inner class 2)     Anonymous inner class 3)     Local inner class (B)Static nested class Example1:-Outer.java class Outer { class Inner { void disp() { System.out.println("Hello This is Inner class Method"); } } public static void main(String[]args) { Inner in=new Inner(); in.disp(); } } Output:- C:\JAVATECH>javac Outer.java Outer.java:12: error: non-static variable this cannot be referenced from a static context Inner in=new Inner(); ...

Inheritance-4

Example10:- class Student { Student() { System.out.println("This is super class Zero argument constructor"); } Student(String s) { System.out.println("This is super class One argument constructor"); } } class Test extends Student { Test() { super(null); System.out.println("This is sub class Zero argument constructor"); } public static void main(String[]args) { Test t=new Test(); } } Output:- C:\JAVATECH>javac Test.java C:\JAVATECH>java Test This is super class One argument constructor This is sub class Zero argument constructor Example11:- class Student { Student() { System.out.println("This is super class Zero argument constructor"); } Student(String s) { System.out.println("This is super class One argument constructor"); } } class Test extends Student { Test() { super(); super(null); System.out.println("This is su...

Small concept about OOPs

Some small concept about OOPs:- In many books and website write about OOPs concepts as hundred percent object oriented, pure object oriented and partial object oriented language. Hundred percent object oriented:- In the hundred percent object oriented movie hero is object, without object program is incomplete that means can not execute program without object. Without class and object programming or application development is not possible. Example of hundred percent object oriented language is  Smalltalk . Pure object oriented:- In the object oriented cinema obviously object is the hero. In pure object oriented language object having same importance but in this having some relax that is without creating object we can successfully execute our application. So in the object oriented programming without class we cannot create or run our application, class is must. Example of pure object oriented language is  Java . Partial object oriented:- In this type of la...
